- Thorin Oakenshield right after the end of the Quest of Erebor (Dragon-sickness or, more probably, Curse of Vengeance);
- Bilbo Baggins at his birthday party, trying to keep the Ring for himself (Dragon-sickness, but maybe also Wandering-madness for his sudden farewell);
- Boromir in Amon Hen, trying to steal the Ring from Frodo (Lure of Power or Dragon-sickness);
- Pippin when looking in the Palantìr (Lure of Secrets);
- Denethor after Faramir is almost fatally injured (undefined - maybe Lure of Power?);
- Frodo at the top of Orodruin (Dragon-sickness). About time for that: it's impressive he didn't suffer any other Bout of madness during the journey!
